Carbon Monoxide Detector Rules for Solar Projects in Montgomery County

Montgomery County in Maryland has strict laws about Carbon Monoxide detectors. This is important for solar energy projects on both commercial and residential properties. Your solar company will apply for a permit (building and electrical permit) to be able to install your solar energy system. Once the solar modules are installed, your solar contractor will request a site visit from the County. The inspector will come to your home or business to check your solar energy system installation.
